DIFFERENT TYPES OF ARDUINO BOARDS AVAILABLE AT TENET TECHNETRONICS

An Arduino is an open-source microcontroller development board. In plain English, you can use the Arduino to read sensors and control things like motors and lights. This allows you to upload programs to this board which can then interact with things in the real world. With this, you can make devices which respond and react to the world at large.

The Arduino platform consists of two parts; the Hardware and the Software, and with these you can build almost anything, from a simple flashing light.

Why is it so popular? Because the hardware is cheap, it’s easy to program and both the software and hardware are easy to learn has led to a large community of users who have contributed code and released instructions for a huge variety of Arduino-based projects. The Arduino boards are available at Tenet store.

The Arduino Boards

Arduino makes several different boards, each with different capabilities. In addition, part of being open source hardware means that others can modify and produce derivatives of Arduino boards that provide even more form factors and functionality.

All Arduino boards have one thing in common: they are programmed through the Arduino IDE. This is the software that allows you to write and upload code. Beyond that, there can be a lot of differences. The number of inputs and outputs (how many sensors, LEDs, and buttons you can use on a single board), speed, operating voltage, and form factor are just a few of the variables.

Why are they different?

Some boards are designed to be embedded and have no programming interface (hardware) which you would need to buy separately. Some can run directly from a 3.7V battery, others need at least 5V. This is a brief overview of some of the more common types of Arduino boards you may encounter:-

1. ARDUINO UNO

The Uno is a great choice for your first Arduino. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

• Physical feature:–

o   14 digital input/output pins (of which 6 can be used as PWM outputs),

o   6 analog inputs,

o   A USB connection,

o   A power jack,

o   A reset button and more.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.

         2.   ARDUINO MEGA

The Arduino Mega is like the UNO’s big brother. It contains everything needed to support the microcontroller. The large number of pins makes this board very handy for projects that require a bunch of digital inputs or outputs (like lots of LEDs or buttons).

• Physical feature:-

o   54 digital input/output pins (14 can be used as PWM outputs),

o   16 analog inputs,

o   A USB connection,

o   A power jack, and

o   A reset button.

1. 3.  ARDIUNO MEGA ADK

The Arduino MEGA ADK is a microcontroller board based on the ATmega2560. Similar to the Mega 2560 and Uno, it features an ATmega8U2 programmed as a USB-to-serial converter.

• Physical features:-

o   USB host interface to connect with Android based phones, based on the MAX3421e IC.

o   54 digital input/output pins (of which 15 can be used as PWM outputs),

o   16 analog inputs, 4 UARTs (hardware serial ports),

o   A 16 MHz crystal oscillator,

o   A USB connection,

o   A power jack,

o   An ICSP header, and

o   A reset button.

       4. ARDUINO NANO

The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x) orATmega168 (Arduino Nano 2.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.

     5.   ARDUINO DUE

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. The Due is compatible with all Arduino shields that work at 3.3V.

• Physical features:-

o   54 digital input/output pins (of which 12 can be used as PWM outputs),

o   12 analog inputs, 4 UARTs (hardware serial ports),

o   A 84 MHz clock,

o   An USB OTG capable connection,

o   2 DAC (digital to analog),

o   2 TWI, a power jack,

o   An SPI header,

o   A JTAG header,

o   A reset button and

o   An erase button.

      6.  ARDUINO LEONARDO

The Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. This means that it can be cheaper and simpler. Also, because the board is handling USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more!.

The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

     7.  ARDUINO YUN

The Arduino Yun is a microcontroller board based on the ATmega32u4 and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named OpenWrt-Yun.

• Physical features:-

o   Built-in Ethernet and WiFi support,

o   A USB-A port,

o   micro-SD card slot,

o   20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs),

o   A 16 MHz crystal oscillator,

o   A micro USB connection,

o   An ICSP header, and

o   A 3 reset buttons.

The Yun is similar to the Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Yun to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

      8.  ARDUINO GALILEO

Galileo is a microcontroller board based on the Intel Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip. It’s the first board based on Intel architecture designed to be hardware and software pin-compatible with Arduino shields designed for the Uno R3.

• Physical Features:-

o   Digital pins 0 to 13 (and the adjacent AREF and GND pins),

o   Analog inputs 0 to 5,

o   The power header,

o   ICSP header, and

o   The UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3. This is also known as the Arduino 1.0 pinout.

Galileo is designed to support shields that operate at either 3.3V or 5V. The core operating voltage of Galileo is 3.3V. However, a jumper on the board enables voltage translation to 5V at the I/O pins. This provides support for 5V Uno shields and is the default behavior. By switching the jumper position, the voltage translation can be disabled to provide 3.3V operation at the I/O pins.

      9.  ARDUINO WIFI SHIELD

The Arduino WiFi Shield connects your Arduino to the internet wirelessly. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. The Arduino WiFi Shield allows an Arduino board to connect to the internet using the 802.11 wireless specifications (WiFi).

• Requires an Arduino board
• Operating voltage 5V (supplied from the Arduino Board)
• Connection via: 802.11b/g networks
• Encryption types: WEP and WPA2 Personal
• Connection with Arduino on SPI port
• on-board micro SD slot
• ICSP headers
• FTDI connection for serial debugging of WiFi shield
• Mini-USB for updating WiFi shield firmware

     10. ARDUINO ETHERNET SHIELD

So you want your Arduino to surf the web but you don’t have room for the Arduino board plus the Ethernet Shield. What do you do? How about giving the Arduino Ethernet a try? The Arduino Ethernet is an Arduino development board with the Wiznet Ethernet interface built in on the same board! It has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator, a RJ45 connection, a power jack, an ICSP header, and a reset button.
